Preconditioning Capacitance Matrix Problems in Domain Imbedding

SIAM Journal on Scientific Computing, 1994
Various preconditioners for the capacitance matrix problems in domain imbedding (DI) are studied. Such preconditioners can be viewed as inverses of the preconditioners for the Schur complement domain decomposition (DD) methods. Preconditioning techniques based on the hierarchical basis (HB), the square root of $ - d^2 /ds^2 $, and on the vector probing

The Kreiss Matrix Theorem on a General Complex Domain

SIAM Journal on Matrix Analysis and Applications, 1999
Let A be a bounded linear operator in a Hilbert space $\H$ with spectrum $\Lam(A)$. The Kreiss matrix theorem gives bounds based on the resolvent norm $\norm{(zI-A)^{-1}}$ for $\norm{A^n}$ if $\Lam(A)$ is in the unit disk or for $\norm{e^{tA}}$ if $\Lam(A)$ is in the left half-plane. We generalize these results to a complex domain $

On the Domain and Dimension Hierarchy of Matrix Interpretations

2012
Matrix interpretations are a powerful technique for proving termination of term rewrite systems. Depending on the underlying domain of interpretation, one distinguishes between matrix interpretations over the real, rational and natural numbers. In this paper we clarify the relationship between all three variants, showing that matrix interpretations ...

A note on matrix domains of Copson matrix of order α and compact operators

Asian-European Journal of Mathematics, 2021
Roopaei [J. Inequal. Appl. 2020 (2020) 120] introduced the sequence space [Formula: see text] which is a matrix domain of Copson matrix in the space [Formula: see text] [Formula: see text] In this paper, we characterize the matrix classes [Formula: see text], [Formula: see text] and [Formula: see text] [Formula: see text].

Holomorphy domain of theS-matrix in potential scattering

Il Nuovo Cimento, 1962
In the present paper we study the holomorphy domain of theS-matrix in the case of potentialsV(z), analytic and conveniently bounded in the right half plane ofz. To this purpose we use a method given byRegge (1).

Structure of Acrosomal Matrix Domains of Rabbit Sperm

Journal of Structural Biology, 1994
The structural organization of different domains of the acrosomal matrix of intact and detergent-extracted rabbit spermatozoa was characterized utilizing both thin sectioning and negative staining techniques. A matrix component with a crystalline substructure was present exclusively within the apical segment of the acrosome.

Cross-Domain Matrix Factorization for Multiple Implicit-Feedback Domains

2015
Cross-domain recommender systems represent an emerging research topic as users generally have interactions with items from multiple domains. One goal of a cross-domain recommender system is to improve the quality of recommendations in a target domain by using user preference information from other source domains.

Modeling the Multiple-Domain Matrix

2009
In order to solve a problem resulting from structural complexity, the scope and implied aspects of the system model in question must be clearly defined. This means that system domains, the level of detail of the elements, and the meaning of the dependencies considered must be determined.

Matrix methods: structure of the domains

2000
Abstract In the first part of this chapter (8.1-8.5) we continue the investigation of the structure of domains which we started in Chapter 2. Whereas in Chapter 2 we made use exclusively of classical methods we now apply functional analytic methods, which we discussed in Chapters 6 and 7.
